High Frequency Aluminum Welding

This video is about ac frequency adjustments and when to use different frequency settings.

High frequency aluminum welding.

And here is another golden rule of thumb. This ends up causing the machine to stall at low amperage since the alternating current loses most of its half cycles when the flow of the current is changed. Hitbox tig welder ac dc pfc wide voltage 65 265v 200a pulse tig stick 4 in 1 multifunction high frequency iron aluminum tig welding machine 4 2 out of 5 stars 10 899 99 899. The process works at the frequency of 250 hz.

Therefore we have developed high frequency linear friction welding hflfw in which a higher frequency than in the case of conventional lfw process is used with the aim to weld high thermal conductivity materials such as aluminum alloys. Gtaw welding aluminum with alternating current high frequency gtaw welding aluminum with alternating current high frequency gas tungsten arc welding gtaw process utilizes heat generated by an electric arc maintained between the workpiece and a nonconsumable ungsten electrode. In general 120 to 200 hz provides an ideal frequency for most aluminum welding. For thinner aluminum or when doing build up on an edge of thin aluminum the higher ac frequency settings can be useful.

If you ve had trouble doing so here are the top 10 mistakes made while tig welding aluminum. Setting the frequency from 120 to 200 hz provides an ideal frequency for most aluminum welding. Frequencies between 80 and 120 hz are comfortable to work with increase control of the arc and boost travel speeds. Https goo gl frdnss in part 2 of our aluminum basics series with weldtube we are talking about ac frequ.

Increasing frequency above 60 hz causes the current to change direction more often which means that it spends less time per cycle in both dcen and dcep mode. By spending less time at each polarity the arc cone has less time to expand. If you have enough amperage an ac frequency setting of 100 120hz is a really good all around setting for most anything.
